Nicolas Cage once blew $150 million on a private island and a dinosaur skull—here's everything he bought

Best known for his roles in movies such as "National Treasure" and "Leaving Las Vegas," Nicolas Cage was once a top earner in Hollywood, worth $150 million.

But Cage didn't hold on to his fortune for long. He squandered it away on a string of expensive and often eccentric purchases, eventually facing foreclosure on several properties and owing the IRS $6.3 million in property taxes.

Now worth around $25 million, Cage is taking roles left and right to help pay off his debts.

Cage once owned 15 residences, including a $25 million waterfront home in Newport Beach, California, a $15.7 million countryside estate in Newport, Rhode Island, and an $8.5 million abode in Las Vegas, pictured below.

Allegedly, Cage also once outbid fellow actor Leonardo DiCaprio for a 70-million-year-old dinosaur skull. The $276,000 artifact turned out to be stolen, however, and Cage had to return it to the Mongolian government.
